LUIVIP OR SLUB CATCHER FOR YARN-WINDING MACHINES.

SPECIFICATION forming part of Letters Patent No. 793,084, dated June27', 1905. Application filed December l, 1904. Serial No. 235,048.

To f1.7/ Uilm/11. fi llmfy/ (l/accru:

Beit known that I, IVILLIAM S. MILLS, a citizen otl the UnitedStates,residing at Bridgeport, in the county ot' Fairfield and State ot'Connecticut, have invented certain new and useful Improvements in Lumpor Slub Catchers for Yarn-IVinding Machines, of which the Vfollowing isa specification.

My invention relates to improvements in IO lump or slub catchers 'foryarn-winding machines; and the main object of my improvement isetliciency in operation, especially with reference to the certainty ot'catching all imperfections in the yarn.

In the accompanying drawings, Figure I is a side elevation ot' myslub-catcher. Fig. 2 is a plan view ot' the same. Fig. 3 is a plan viewot' the same with the card-clothing plate turned back, so as to be outof action. Fig. a is a transverse section otl the guiding-plate on theline ,1' ,n ot' Fig. 3 with an elevation ot' the parts lying beyond thesaid line.

A designates the guiding-plate, that forms the base ot' my slub-catcher.It is provided with ears by means ot' which and proper screws or rivetsit may be attached to the guide-bar of any ordinary yarn-winding machineand in a position to have the yarn or thread drawn tautly over thesmooth or polished face 6 ofthe said plate A. This polished face of thesaid plate has a fiat middle portion with a rounded portion at each edgethereof.

At one end ot' the guiding-plate A there is a pair of bracket-ears 7,within which I pivot the lever 8 on the pin l5. A card-clothing plate 9is pivoted tothe middle portion ol the said lever 8 by means of pintle16 and lugs l0, that project upwardly from the said plate 9 near oneend. The opposite end ot' the cardclothing plate 9 is provided with anadjustingscrew 1l and set-nut l2. A like adjustingscrew 13 and set-nutla are arranged in that end of the lever 8 which is farthest from thebracket-ears 7. The end ot' the adjusting- LS screw 13 bears on the topof the'card-clothing plate 9, as shown in Fig. l, whereby the saidcard-clothing plate may be adjusted to the desired distance 'from thetop face 6 ot' the guiding-plate and also so adjusted as to be parallelto the said plate with reference to the length of the said parts. Apiece of sharp-pointed card-clothing 17 or an equivalent series ot'sharp-pointed teeth is secured to the under t'ace of the card-clothingplate, as shown.

To use the slab-catcher. it is secured to the guide-bar or other part ofa winding-machine, so that the thread or yarn may be drawn tautly overthe top face ot' the guiding-plate A as it passes to the spool or bobbinon which it is wound. By means of the adjusting-screws l1 60 and 13 thecard-clothing is adjusted to bring the plane ot' its points or teeth atagiven distance from the face 6 of the plate A when the parts are in theposition shown in Figs. l and 2. This distance will be greater or less,accoi-ding to the size or thickness ot' the yarn to be wound. A gage inthe form ot' a at plate and ot' the same thickness as the yarn to bewound may be used in adjusting the cardclothing to the guiding-plate,the said gage being' placed on theguiding-plate to adjust the points andremoved after adjustment. The screws ll and .13 serve as stops to limitthe downward movement of the outer ends of the card-clothing plate 9 andlever 8. vWhen the 75 gage-plate is to be used, the screws should beturned back far enough to be out of the way. After bringing thecard-clothing plate 9 down level on the top of the gage-plate the screwscan be turned down until they come to their SO bearings and the set-nutstightened up. The gage-plate may now be removed, and the device is readyt'or use. Turning down the screw ll will raise the outer ends of thecardelothing plate 9 and the lever 8. Then turn- 85 ing down the screw13 will raise the outer end otl the lever 1S and lower the pivoted endot' the card-clothing plate 9. lVith the parts thus placed and adjusted,as shown in Fig. 1, the yarn passes along between the guidingplate andpoints of the card-clothing without obstruction so long as it is evenand free from lumps or slubs. Them however, a lump or slub thicker thanthe regular size of yarn reaches the guiding-plate, it is caught bythecard-clothing. The operator then turns the level S and attached partsover into the position shown in Figs. 3 and 4, pulls otl' the yarn,

and breaks out the bad place. is again readjusted for winding, the leverand connecting parts are turned back again into the position shown inFigs. l and 2.

The main advantage of this Construction is the certainty of catching allthe lumps or slubs, thereby insuring a clean yarn. All danger ofbreaking needles and such other trouble as results from the yarn notbeing freed from lum ps and slubs is avoided by the employment of mycatcher.

I claim as my invention# l. The combination of a guiding-plate with alever pivotally mounted on the said guidingplate, and a card-clothingplate pivotally conneoted to the said lever, and means for ad- 1 Vhenthe yarn 1 justing the said card-clothing plate and lever on theirpivots, substantially as described.

2. The combination of the guiding-plate With the lever pivotallyconnected by one end with the said guid e-plate, a card-clothing platepivotally Connected to the said lever and the two adjusting-screwsmounted near the respective ends ofthe said lever and card-clothingplate, the screw in the card-clothing plate being resisted by theguiding-plate and the screw in the lever being resisted by thecardolothing plate.
